Which term is the complete scan of the ultrasound beam, producing a single image made up of multiple scan lines?

• A. Frame
• B. Cine Loop
• C. Field of View
• D. Comet Tail

Answer: (A)

A frame is the complete ultrasound image formed from all scan lines collected during one sweep. Each scan line samples echoes along a path, and when those lines are combined across the image plane, they create one frame—a snapshot of the anatomy at that moment. If you collect and review many frames in sequence, you get a cine loop to visualize motion. The field of view simply describes the display area of the image—the width and height of what’s shown, set by depth and sector angle—not the complete image itself. A comet tail is an artifact arising from strong reflectors that produce a bright, tail-like streak.
